Mil Is Childcare And Has Blocked Me

In MD. My soon to be ex and I have not yet filed, although I have a final protective order that I have legal and physical custody, he has supervised visitation, supervised by his parents at their home. He cannot contact me unless it's about visitation and it has to be through a parenting app. Over the winter break he was in violation of the order and my attorney reached out to clarify the order because it has been in effect less than a month.

His mom has been the main childcare provider for our children during the school year, and as of today (the day after my attorney spoke to him) it looks like she's blocked me. Personally I'm not bothered by it but it will make it difficult to contact her regarding childcare/our children being there. Him and his family have been very high conflict over the years. I don't want to jump to conclusions and pull our children out of their routine, which is why I have continued with this arrangement. However there have been multiple instances that his mom has gotten in my face and screamed at me. I'm not looking forward to Monday morning if I show up like normal but she has decided to block me/has taken issue with me. but I don't know if i should try to contact her via email and say something about no longer feeling comfortable with the childcare arrangement? I have reached out to my attorney but I am also just seeking advice on what to do or not do.
